Comparing: IS-7 vs. (R) AMX 50 B

Development of the IS-7 started in the spring of 1945. Prototypes successfully underwent trials in 1946 and 1947. However, the IS-7 never saw mass production.

Developed starting in 1951 by DEFA, the state weapons design bureau. By 1958, the AMX 50 B received a number of improvements, including a low-profile cast hull and torsion-bar suspension. A new oscillating turret with a 120-mm gun was also mounted on the vehicle. Despite the fact that the Maybach engine power provided just 1000 hp, the specialists from the German Gruppe M company were looking for a solution that would allow the vehicle to reach the speed up to 65 km/h. Only one finished prototype of this variant was built.
